Golang framework source code architecture analysis

This article analyzes the source code architecture of a popular Golang framework, which follows the classic layered architecture: HTTP layer: processing requests and routing. Routing layer: defines routing and scheduling requests. Control layer: Contains business logic and model interaction. Model layer: manages database interactions and data. Base layer: Provides core functionality such as logging and dependency injection.

Golang framework source code architecture analysis

In the world of software development, framework is an indispensable tool for building robust and maintainable applications. Programs provide the foundation. There are many excellent frameworks in Golang that simplify the development process and allow developers to focus on business logic rather than infrastructure.

This article will deeply analyze the source code architecture of a popular Golang framework to understand its inner workings. We'll break down the key components of the framework and explore how they work together to provide an efficient and easy-to-use development environment.

Framework Architecture

The framework follows the classic layered architecture, dividing the application into the following layers:

• HTTP layer: Responsible HTTP requests are processed and routed to the appropriate handler.
• Routing layer: Define routing and dispatch requests to the correct control layer.
• Control layer: Contains the business logic of the application and interacts with the model layer.
• Model layer: Responsible for interacting with the database and managing data.
• Base layer: Provides the core functionality of the framework, such as logging, configuration, and dependency injection.

Practical Case: Creating a CRUD API

In order to better understand how this architecture works, we create a simple CRUD (Create, Read, Update, Delete) API:

package main

import (
    "context"
    "fmt"
    "net/http"

    "github.com/gorilla/mux"
    "go.mongodb.org/mongo-driver/bson"
    "go.mongodb.org/mongo-driver/mongo"
    "go.mongodb.org/mongo-driver/mongo/options"
)

// 定义数据模型
type Post struct {
    ID        string `bson:"_id"`
